Description

Die Erfindung betrifft einen Modulsatz für den Bau von Leistungsschaltern.The invention relates to a module set for the construction of circuit breakers.

Leistungsschalter, wie z. B. aus der US 6 373 015 B1 , der US 3 864 534 A , der US 5 357 068 A , und der WO 2016/116351 A1 bekannt, sind elektrische Schalter, die für hohe elektrische Ströme und Spannungen ausgelegt sind, um insbesondere hohe Überlastströme und Kurzschlussströme sicher abschalten zu können. Dazu weisen Leistungsschalter eine Vielfalt von Baugruppen auf, die in Abhängigkeit von den Anforderungen an den jeweiligen Leistungsschalter stark differieren. Zu derartigen Baugruppen gehören beispielsweise Schalteinheiten zum Öffnen und Schließen von Strompfaden, Isolatoren zur elektrischen Isolation von Schalteinheiten und kinematische Ketten zum Verbinden von Schalteinheiten mit Antrieben für bewegbare Schaltelemente der Schalteinheiten.Circuit breakers, such as those from the US 6 373 015 B1 , the US 3 864 534 A , the US 5 357 068 A , and the WO 2016/116351 A1 are electrical switches that are designed for high electrical currents and voltages in order to be able to safely switch off high overload currents and short-circuit currents in particular. For this purpose, circuit breakers have a variety of components that differ greatly depending on the requirements of the respective circuit breaker. Such components include, for example, switching units for opening and closing current paths, insulators for electrically insulating switching units and kinematic chains for connecting switching units with drives for movable switching elements of the switching units.

Der Erfindung liegt die Aufgabe zugrunde, den Bau von Leistungsschaltern zu vereinfachen und die Kosten für den Bau von Leistungsschaltern zu reduzieren.The invention is based on the object of simplifying the construction of circuit breakers and reducing the costs for the construction of circuit breakers.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved according to the invention by the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Ein erfindungsgemäßer Modulsatz für den Bau von Leistungsschaltern umfasst einen Schalteinheitstyp baugleicher Schalteinheiten, wenigstens einen Schalteinheitssockeltyp baugleicher Schalteinheitssockel, die jeweils mit einer Schalteinheit verbindbar sind, und wenigstens einen Schalteinheitssockeladaptertyp baugleicher Schalteinheitssockeladapter, die jeweils mit einer Schalteinheit und einem Schalteinheitssockel verbindbar sind.A module set according to the invention for the construction of circuit breakers comprises a switching unit type of identical switching units, at least one switching unit base type of identical switching unit base, which can each be connected to a switching unit, and at least one switching unit base adapter type of identical switching unit base adapter, which can each be connected to a switching unit and a switching unit base.

Die Erfindung ermöglicht den Bau verschiedener Leistungsschalter mit den Modulen eines Modulsatzes. Der Modulsatz weist wenigstens einen Schalteinheitssockeltyp baugleicher Schalteinheitssockel und wenigstens einen Schalteinheitssockeladaptertyp baugleicher Schalteinheitssockeladapter für einen Schalteinheitstyp baugleicher Schalteinheiten auf. Damit können durch verschiedene Kombinationen von Schalteinheitssockeln und Schalteinheitssockeladaptern mit einer Schalteinheit verschiedene Unterbrechereinheiten für Leistungsschalter gebaut werden. Insbesondere ermöglicht die Erfindung, eine Schalteinheit direkt oder über einen Schalteinheitssockeladapter mit einem Schalteinheitssockel zu verbinden. Dadurch kann ein relativ einfach gestalteter Schalteinheitssockeladapter bedarfsweise als Verlängerung eines relativ komplexen Schalteinheitssockels eingesetzt werden, so dass weniger verschiedene Schalteinheitssockel bereitgehalten werden müssen. Dies reduziert vorteilhaft die Kosten für den Bau von für verschiedene Anforderungen ausgelegten Leistungsschaltern.The invention enables the construction of various circuit breakers with the modules of a module set. The module set has at least one switching unit base type of identical switching unit base and at least one switching unit base adapter type of identical switching unit base adapter for a switching unit type of identical switching units. This means that various interrupter units for circuit breakers can be built using various combinations of switching unit bases and switching unit base adapters with a switching unit. In particular, the invention enables a switching unit to be connected to a switching unit base directly or via a switching unit base adapter. This means that a relatively simply designed switching unit base adapter can be used as an extension of a relatively complex switching unit base if required, so that fewer different switching unit bases have to be kept on hand. This advantageously reduces the costs of building circuit breakers designed for different requirements.

Die Erfindung sieht mehrere Schalteinheitssockeladaptertypen vor, wobei die Schalteinheitssockeladapter unterschiedlicher Schalteinheitssockeladaptertypen unterschiedliche Längen aufweisen. Dadurch kann vorteilhaft die Anzahl herzustellender Schalteinheitssockel durch eine größere Vielfalt von Schalteinheitssockeladaptern verschiedener Längen vorteilhaft reduziert werden.The invention provides several switching unit base adapter types, wherein the switching unit base adapters of different switching unit base adapter types have different lengths. As a result, the number of switching unit bases to be produced can advantageously be reduced by a larger variety of switching unit base adapters of different lengths.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Schalteinheitssockeladapter jeweils lösbar, beispielsweise durch Schraubverbindungen, mit einer Schalteinheit und/oder mit einem Schalteinheitssockel verbindbar sind. Diese Ausgestaltung der Erfindung ermöglicht vorteilhaft eine einfache und flexible Verlängerung von Schalteinheitssockeln durch Schalteinheitssockeladapter.A further embodiment of the invention provides that the switching unit base adapters can each be detachably connected to a switching unit and/or to a switching unit base, for example by means of screw connections. This embodiment of the invention advantageously enables a simple and flexible extension of switching unit bases by means of switching unit base adapters.

Die Erfindung sieht vor, dass die Schalteinheiten jeweils einen ersten Nennstromkontakt, ein mit dem ersten Nennstromkontakt elektrisch verbundenes stiftartiges erstes Lichtbogenkontaktstück, einen zweiten Nennstromkontakt und ein mit dem zweiten Nennstromkontakt elektrisch verbundenes hohles zweites Lichtbogenkontaktstück aufweisen. Dadurch umfasst der Modulsatz Schalteinheiten eines üblichen Typs, die für den Bau von Leistungsschaltern in vielen unterschiedlichen Anwendungen geeignet sind.The invention provides that the switching units each have a first rated current contact, a pin-like first arcing contact piece electrically connected to the first rated current contact, a second rated current contact and a hollow second arcing contact piece electrically connected to the second rated current contact. The module set therefore comprises switching units of a conventional type that are suitable for the construction of circuit breakers in many different applications.

Eine Weitergestaltung der vorgenannten Ausgestaltung der Erfindung sieht einen ersten Schalteinheitssockeltyp baugleicher erster Schalteinheitssockel vor, die jeweils zum Tragen des ersten Nennstromkontakts und des ersten Lichtbogenkontaktstücks einer Schalteinheit ausgebildet sind. Ferner sieht diese Ausgestaltung der Erfindung einen zweiten Schalteinheitssockeltyp baugleicher zweiter Schalteinheitssockel vor, die jeweils zur bewegbaren Lagerung des zweiten Nennstromkontakts und des zweiten Lichtbogenkontaktstücks einer Schalteinheit ausgebildet sind. Dabei können die Schalteinheitssockeladapter jeweils ein erstes Schalteinheitssockeladapterende, das zum Tragen des ersten Nennstromkontakts und des ersten Lichtbogenkontaktstücks einer Schalteinheit ausgebildet ist, und ein zweites Schalteinheitssockeladapterende, das mit einem ersten Schalteinheitssockel verbindbar ist, aufweisen. Diese Ausgestaltungen der Erfindung berücksichtigen, dass Schalteinheitssockel für feststehende und bewegbare Nennstromkontakte unterschiedlichen Anforderungen genügen und daher unterschiedlich gestaltet sind. Außerdem berücksichtigen sie, dass Schalteinheitssockel für feststehende Nennstromkontakte in der Regel einfacher als Schalteinheitssockel für bewegbare Nennstromkontakte gestaltet werden können und daher auch einfacher durch Schalteinheitssockeladapter verlängerbar sind als Schalteinheitssockel für bewegbare Nennstromkontakte.A further development of the aforementioned embodiment of the invention provides a first switching unit base type of identical first switching unit bases, each of which is designed to support the first rated current contact and the first arcing contact piece of a switching unit. Furthermore, this embodiment of the invention provides a second switching unit base type of identical second switching unit bases, each of which is designed to movably support the second rated current contact and the second arcing contact piece of a switching unit. The switching unit base adapters can each have a first switching unit base adapter end, which is designed to support the first rated current contact and the first arcing contact piece of a switching unit, and a second switching unit base adapter end, which can be connected to a first switching unit base. These embodiments of the invention take into account that switching unit bases for fixed and movable rated current contacts meet different requirements and are therefore designed differently. They also take into account that switch unit bases for fixed rated current contacts can generally be designed more simply than switch unit bases for movable rated current contacts and can therefore also be extended more easily using switch unit base adapters than switch unit bases for movable rated current contacts.

Eine weitere Ausgestaltung der Erfindung sieht einen Kettentyp baugleicher kinematischer Ketten zum Verbinden eines Antriebs eines Leistungsschalters mit wenigstens einem bewegbaren Schaltelement einer Schalteinheit vor. Dadurch wird vorteilhaft die Anzahl verschiedener kinematischer Ketten reduziert. Die Reduzierung wird durch die Verwendung baugleicher Schalteinheiten und Schalteinheitssockel ermöglicht.A further embodiment of the invention provides a chain type of identical kinematic chains for connecting a drive of a circuit breaker to at least one movable switching element of a switching unit. This advantageously reduces the number of different kinematic chains. The reduction is made possible by using identical switching units and switching unit bases.

Mit anderen Worten sieht diese Ausgestaltung der Erfindung vorteilhaft vor, für Unterbrechereinheiten, die aus unterschiedlichen Kombinationen von Schalteinheitssockeln und Schalteinheitssockeladaptern mit jeweils einer Schalteinheit gebaut werden, entsprechende Unterbrechereinheitsisolatorröhren vorzuhalten.A further embodiment of the invention provides several interrupter unit tube types, each of identical interrupter unit insulator tubes, which are each designed to accommodate an interrupter unit that has either a switching unit and at least one switching unit base or a switching unit, at least one switching unit base and at least one switching unit base adapter. In other words, this embodiment of the invention advantageously provides for the provision of corresponding interrupter unit insulator tubes for interrupter units that are built from different combinations of switching unit bases and switching unit base adapters, each with a switching unit.

Eine weitere Ausgestaltung der Erfindung sieht einen Verbindungsgehäusetyp baugleicher Verbindungsgehäuse vor, die jeweils zum Verbinden zweier Unterbrechereinheiten eines Leistungsschalters ausgebildet sind. Diese Ausgestaltung der Erfindung ermöglicht vorteilhaft, Unterbrechereinheiten, die aus Modulen des Modulsatzes gebaut werden, durch entsprechende Verbindungsgehäuse des Modulsatzes miteinander zu verbinden, beispielsweise um Unterbrechereinheiten miteinander zu verschalten und dadurch die Anzahl unterschiedlicher Module zum Bau verschiedener Leistungsschalter weiter zu reduzieren.A further embodiment of the invention provides a connection housing type of identical connection housings, each of which is designed to connect two interrupter units of a circuit breaker. This embodiment of the invention advantageously makes it possible to connect interrupter units that are built from modules of the module set to one another using corresponding connection housings of the module set, for example in order to interconnect interrupter units and thereby further reduce the number of different modules for building different circuit breakers.

Eine weitere Ausgestaltung der Erfindung sieht einen Einschaltwiderstandstyp baugleicher Einschaltwiderstände, wenigstens einen Einschaltwiderstandssockeltyp baugleicher Einschaltwiderstandssockel, die jeweils mit einem Einschaltwiderstand verbindbar sind, und wenigstens einen Einschaltwiderstandssockeladaptertyp baugleicher Einschaltwiderstandssockeladapter, die jeweils mit einem Einschaltwiderstand und einem Einschaltwiderstandssockel verbindbar sind, vor.

Die Ausgestaltung und Funktion dieser Module werden unten näher beschrieben.The design and function of these modules are described in more detail below.

Figur 2 zeigt schematisch eine Schnittdarstellung eines ersten Ausführungsbeispiels eines Leistungsschalters 100. Der Leistungsschalter 100 weist zwei erste Unterbrechereinheiten 31, eine vertikale Isolatorsäule 35, einen Antrieb 37, einen Steuerschrank 39 mit Steuerkomponenten zur Steuerung des Leistungsschalters 100 und einen Tragstiel 41 auf. Figure 2 shows schematically a sectional view of a first embodiment of a circuit breaker 100. The circuit breaker 100 has two first interrupter units 31, a vertical insulator column 35, a drive 37, a control cabinet 39 with control components for controlling the circuit breaker 100 and a support post 41.

Jede erste Unterbrechereinheit 31 weist eine Schalteinheit 3, einen ersten Schalteinheitssockel 5, einen zweiten Schalteinheitssockel 7 und eine erste Unterbrechereinheitsisolatorröhre 13 des Modulsatzes 1 auf. Die Schalteinheit 3 ist zwischen dem ersten Schalteinheitssockel 5 und dem zweiten Schalteinheitssockel 7 montiert. Die Schalteinheit 3 und die Schalteinheitssockel 5, 7 sind in einer ersten Unterbrechereinheitsisolatorröhre 13 angeordnet.Each first breaker unit 31 comprises a switching unit 3, a first switching unit base 5, a second switching unit base 7 and a first breaker unit insulator tube 13 of the module set 1. The switching unit 3 is mounted between the first switching unit base 5 and the second switching unit base 7. The switching unit 3 and the switching unit bases 5, 7 are arranged in a first breaker unit insulator tube 13.

Die beiden ersten Unterbrechereinheiten 31 sind durch ein Verbindungsgehäuse 17 miteinander verbunden, von dem auf sich gegenüberliegenden Seiten die ersten Unterbrechereinheitsisolatorröhren 13 der beiden ersten Unterbrechereinheiten 31 horizontal abstehen.The two first interrupter units 31 are connected to one another by a connecting housing 17, from which the first interrupter unit insulator tubes 13 of the two first interrupter units 31 protrude horizontally on opposite sides.

Das Verbindungsgehäuse 17 ist an einem oberen Ende der Isolatorsäule 35 angeordnet. Der Antrieb 37, der Steuerschrank 39 und das untere Ende der Isolatorsäule 35 sind an dem Tragstiel 41 angeordnet. Der Antrieb 37 ist über eine durch die Isolatorsäule 35 geführte Koppelstange 43 mit einer kinematischen Kette 11 des Modulsatzes 1 verbunden, die mit bewegbaren Schaltelementen der Schalteinheiten 3 verbunden ist. Über die Koppelstange 43 und die kinematische Kette 11 sind die bewegbaren Schaltelemente der Schalteinheiten 3 durch den Antrieb 37 gleichzeitig antreibbar, um durch die Bewegung der Schaltelemente miteinander in Reihe geschaltete Strompfade der beiden ersten Unterbrechereinheiten 31 zu öffnen oder zu schließen.The connection housing 17 is arranged at an upper end of the insulator column 35. The drive 37, the control cabinet 39 and the lower end of the insulator column 35 are arranged on the support post 41. The drive 37 is connected to a kinematic chain 11 of the module set 1 via a coupling rod 43 guided through the insulator column 35, which is connected to movable switching elements of the switching units 3. The movable switching elements of the switching units 3 can be driven simultaneously by the drive 37 via the coupling rod 43 and the kinematic chain 11 in order to open or close current paths of the two first interrupter units 31 that are connected in series with one another by the movement of the switching elements.

Die Figuren 3 und 4 zeigen schematische Schnittdarstellungen weitere Ausführungsbeispiele von Leistungsschaltern 100. Die in den Figuren 3 und 4 dargestellten Leistungsschalter 100 unterscheiden sich von dem in Figur 2 dargestellten Leistungsschalter 100 lediglich durch die Ausführung ihrer Unterbrechereinheiten 32, 33 und sind daher nur in dem Bereich der Unterbrechereinheiten 32, 33 dargestellt.The Figures 3 and 4 show schematic sectional views of further embodiments of circuit breakers 100. The Figures 3 and 4 The circuit breakers 100 shown in the diagram differ from the circuit breaker Figure 2 The circuit breakers 100 shown only by the design of their interrupter units 32, 33 and are therefore only shown in the area of the interrupter units 32, 33.

Figur 3 zeigt einen Leistungsschalter 100 mit zwei zweiten Unterbrechereinheiten 32, die jeweils eine Schalteinheit 3, einen ersten Schalteinheitssockel 5, einen zweiten Schalteinheitssockel 7, einen ersten Schalteinheitssockeladapter 9 und eine zweite Unterbrechereinheitsisolatorröhre 14 des Modulsatzes 1 aufweisen. Der erste Schalteinheitssockeladapter 9 jeder zweiten Unterbrechereinheit 32 ist in unten näher beschriebener Weise zwischen die Schalteinheit 3 und den ersten Schalteinheitssockel 5 montiert. Die Schalteinheit 3 ist zwischen den ersten Schalteinheitssockeladapter 9 und den zweiten Schalteinheitssockel 7 montiert. Figure 3 shows a circuit breaker 100 with two second interrupter units 32, each of which has a switching unit 3, a first switching unit base 5, a second switching unit base 7, a first switching unit base adapter 9 and a second interrupter unit insulator tube 14 of the module set 1. The first switching unit base adapter 9 of each second interrupter unit 32 is mounted between the switching unit 3 and the first switching unit base 5 in a manner described in more detail below. The switching unit 3 is mounted between the first switching unit base adapter 9 and the second switching unit base 7.

Figur 4 zeigt einen Leistungsschalter 100 mit zwei dritten Unterbrechereinheiten 33, die jeweils eine Schalteinheit 3, einen ersten Schalteinheitssockel 5, einen zweiten Schalteinheitssockel 7, einen zweiten Schalteinheitssockeladapter 10 und eine dritte Unterbrechereinheitsisolatorröhre 15 des Modulsatzes 1 aufweisen. Der zweite Schalteinheitssockeladapter 10 jeder dritten Unterbrechereinheit 33 ist analog zu einem ersten Schalteinheitssockeladapter 9 der Figur 3 zwischen die Schalteinheit 3 und den ersten Schalteinheitssockel 5 montiert. Die Schalteinheit 3 ist zwischen den zweiten Schalteinheitssockeladapter 10 und den zweiten Schalteinheitssockel 7 montiert. Figure 4 shows a circuit breaker 100 with two third interrupter units 33, each of which has a switching unit 3, a first switching unit base 5, a second switching unit base 7, a second switching unit base adapter 10 and a third interrupter unit insulator tube 15 of the module set 1. The second switching unit base adapter 10 of each third interrupter unit 33 is analogous to a first switching unit base adapter 9 of the Figure 3 mounted between the switching unit 3 and the first switching unit base 5. The switching unit 3 is mounted between the second switching unit base adapter 10 and the second switching unit base 7.

Figur 5 zeigt ein weiteres Ausführungsbeispiel eines Leistungsschalters 100. Dieser Leistungsschalter 100 weist zwei Paare von zweiten Unterbrechereinheiten 32 auf, die jeweils wie die zweiten Unterbrechereinheiten 32 des in Figur 3 gezeigten Ausführungsbeispiels ausgebildet sind. Die beiden Paare zweiter Unterbrechereinheiten 32 sind durch eine elektrische Verbindungsleitung 44 miteinander verbunden, so dass die Strompfade aller vier Unterbrechereinheiten 32 des Leistungsschalters 100 elektrisch in Reihe geschaltet sind. Figure 5 shows a further embodiment of a circuit breaker 100. This circuit breaker 100 has two pairs of second interrupter units 32, each of which is designed like the second interrupter units 32 of the circuit breaker shown in Figure 3 The two pairs of second interrupter units 32 are connected to one another by an electrical connecting line 44, so that the current paths of all four interrupter units 32 of the circuit breaker 100 are electrically connected in series.

Die Figuren 2 bis 5 zeigen beispielhaft, dass mit dem Modulsatz 1 Leistungsschalter 100 mit unterschiedlichen Unterbrechereinheiten 31, 32, 33 gebaut werden können. Wesentlich ist dabei insbesondere, dass der Modulsatz 1 Schalteinheitssockeladapter 9, 10 aufweist, die jeweils zwischen eine Schalteinheit 3 und einen ersten Schalteinheitssockel 5 montierbar sind und als Verlängerungsstücke der ersten Schalteinheitssockel 5 dienen. Dadurch brauchen für unterschiedliche Unterbrechereinheiten 31, 32, 33 keine unterschiedliche erste Schalteinheitssockel 5 bereitgestellt werden. Die ersten Schalteinheitssockeladapter 9 und zweiten Schalteinheitssockeladapter 10 unterscheiden sich voneinander durch ihre Länge und können daher verwendet werden, um unterschiedliche Verlängerungen eines ersten Schalteinheitssockels 5 zu erreichen. Selbstverständlich kann der Modulsatz 1 auch eine verschiedene Anzahl unterschiedlicher Schalteinheitssockeladaptertypen aufweisen. Die Unterbrechereinheitsröhrentypen unterscheiden sich entsprechend durch die Längen ihrer Unterbrechereinheitsisolatorröhren 13, 14, 15.The Figures 2 to 5 show by way of example that circuit breakers 100 with different interrupter units 31, 32, 33 can be built with the module set 1. It is particularly important that the module set 1 has switching unit base adapters 9, 10, which can each be mounted between a switching unit 3 and a first switching unit base 5 and serve as extension pieces of the first switching unit base 5. As a result, different first switching unit bases 5 do not need to be provided for different interrupter units 31, 32, 33. The first switching unit base adapters 9 and second switching unit base adapters 10 differ from one another in terms of their length and can therefore be used to achieve different extensions of a first switching unit base 5. Of course, the module set 1 can also have a different number of different switching unit base adapter types. The interrupter unit tube types differ accordingly by the lengths of their interrupter unit insulator tubes 13, 14, 15.

Analog zum Bau unterschiedlicher Unterbrechereinheiten 31, 32 33 können mit dem Modulsatz unterschiedliche Einschaltwiderstandseinheiten gebaut werden, die jeweils einen Einschaltwiderstand 19, einen ersten Einschaltwiderstandssockel 21, einen zweiten Einschaltwiderstandssockel 23, eine Einschaltwiderstandsisolatorröhre 27, 28, 29 und gegebenenfalls wenigstens einen Einschaltwiderstandssockeladapter 24, 25 aufweisen. Analog zu dem Aufbau der Unterbrechereinheiten 31, 32 33 ist dabei jeweils der Einschaltwiderstand 19 zwischen einen ersten Einschaltwiderstandssockel 21 und einen zweiten Einschaltwiderstandssockel 23 montiert, wobei zwischen den Einschaltwiderstand 19 und einen Einschaltwiderstandssockel 21, 23 ferner ein Einschaltwiderstandssockeladapter 24, 25 montiert sein kann.Analogous to the construction of different interrupter units 31, 32 33, different on-resistance units can be built with the module set, each of which has an on-resistance 19, a first on-resistance base 21, a second on-resistance base 23, an on-resistance insulator tube 27, 28, 29 and optionally at least one on-resistance base adapter 24, 25. Analogous to the construction of the interrupter units 31, 32 33, the on-resistance 19 is mounted between a first on-resistance base 21 and a second on-resistance base 23, wherein an on-resistance base adapter 24, 25 can also be mounted between the on-resistance 19 and an on-resistance base 21, 23.

Figur 6 zeigt eine Schnittdarstellung einer ersten Unterbrechereinheit 31. Die Schalteinheit 3 weist einen ersten Nennstromkontakt 51, ein mit dem ersten Nennstromkontakt 51 elektrisch verbundenes stiftartiges erstes Lichtbogenkontaktstück 53, einen zweiten Nennstromkontakt 55 und ein mit dem zweiten Nennstromkontakt 55 elektrisch verbundenes hohles zweites Lichtbogenkontaktstück 57 auf. Der zweite Nennstromkontakt 55 und die beiden Lichtbogenkontaktstück 53, 57 sind die bewegbaren Schaltelemente der Schalteinheit 3. Figure 6 shows a sectional view of a first interrupter unit 31. The switching unit 3 has a first rated current contact 51, a first rated current contact 51 electrically connected pin-like first arcing contact piece 53, a second rated current contact 55 and a hollow second arcing contact piece 57 electrically connected to the second rated current contact 55. The second rated current contact 55 and the two arcing contact pieces 53, 57 are the movable switching elements of the switching unit 3.

In Figur 6 ist ein Schaltzustand dargestellt, in dem der Strompfad der Schalteinheit 3 nicht geschlossen ist. Zum Schließen des Strompfads werden der zweite Nennstromkontakt 55 und das zweite Lichtbogenkontaktstück 57 über die kinematische Kette 11, die hier nur teilweise dargestellt ist, auf den ersten Nennstromkontakt 51 und das erste Lichtbogenkontaktstück 53 zu (in Figur 6 nach rechts) bewegt bis zunächst die Nennstromkontakte 51, 55 einander kontaktieren und danach das erste Lichtbogenkontaktstück 53 in das zweite Lichtbogenkontaktstück 57 einfährt. Das erste Lichtbogenkontaktstück 53 wird ebenfalls bewegt, jedoch in entgegengesetzter Richtung (in Figur 6 nach links) auf das das zweite Lichtbogenkontaktstück 57 zu. Dazu dient ein Koppelmechanismus, der die Bewegung des ersten Lichtbogenkontaktstück 53 an die Bewegung des zweiten Nennstromkontakts 55 und des zweiten Lichtbogenkontaktstücks 57 koppelt, aber die Bewegungsrichtung umkehrt. Zur Umkehrung der Bewegungsrichtung umfasst der Koppelmechanismus einen Umlenkhebel 59, in den ein mit dem zweiten Nennstromkontakt 55 und dem zweiten Lichtbogenkontaktstück 57 bewegter Koppelstift 61 einfährt.In Figure 6 a switching state is shown in which the current path of the switching unit 3 is not closed. To close the current path, the second rated current contact 55 and the second arcing contact piece 57 are moved via the kinematic chain 11, which is only partially shown here, to the first rated current contact 51 and the first arcing contact piece 53 (in Figure 6 to the right) until the rated current contacts 51, 55 contact each other and then the first arcing contact piece 53 moves into the second arcing contact piece 57. The first arcing contact piece 53 is also moved, but in the opposite direction (in Figure 6 to the left) towards the second arcing contact piece 57. A coupling mechanism is used for this purpose, which couples the movement of the first arcing contact piece 53 to the movement of the second rated current contact 55 and the second arcing contact piece 57, but reverses the direction of movement. To reverse the direction of movement, the coupling mechanism comprises a deflection lever 59, into which a coupling pin 61 moves, which is moved with the second rated current contact 55 and the second arcing contact piece 57.

Der erste Schalteinheitssockel 5 trägt den ersten Nennstromkontakt 51 und damit auch das mit dem ersten Nennstromkontakt 51 bewegbar verbundene erste Lichtbogenkontaktstück 53. Der erste Schalteinheitssockel 5 ist mit einem von dem Verbindungsgehäuse 17 abgewandten Ende der ersten Unterbrechereinheitsisolatorröhre 13 verbunden.The first switching unit base 5 carries the first rated current contact 51 and thus also the first arcing contact piece 53 movably connected to the first rated current contact 51. The first switching unit base 5 is connected to an end of the first interrupter unit insulator tube 13 facing away from the connection housing 17.

Der zweite Schalteinheitssockel 7 lagert den zweiten Nennstromkontakt 55 und das zweite Lichtbogenkontaktstück 57, so dass diese über die kinematische Kette 11 bewegbar sind. Der zweite Schalteinheitssockel 7 ist mit einem dem Verbindungsgehäuse 17 zugewandten Ende der ersten Unterbrechereinheitsisolatorröhre 13 verbunden.The second switch unit base 7 supports the second rated current contact 55 and the second arc contact piece 57 so that they can be moved via the kinematic chain 11. The second switch unit base 7 is connected to an end of the first interrupter unit insulator tube 13 facing the connection housing 17.

Die ersten Unterbrechereinheitsisolatorröhren 13 können wie auch die weiteren Unterbrechereinheitsisolatorröhren 14, 15 beispielsweise als Porzellan- oder Verbundisolatoren ausgeführt sein.The first interrupter unit insulator tubes 13, as well as the further interrupter unit insulator tubes 14, 15, can be designed, for example, as porcelain or composite insulators.

Figur 7 zeigt eine Schnittdarstellung eines Ausführungsbeispiels eines zweiten Schalteinheitssockels 7. Der zweite Schalteinheitssockel 7 weist an seinem verbindungsgehäuseseitigen Ende einen Verbindungsflansch 63 auf, der mit einer Unterbrechereinheitsisolatorröhre 13, 14, 15 verbindbar ist. An dem von dem Verbindungsgehäuse 17 abgewandten Ende weist der zweite Schalteinheitssockel 7 einen elektrisch leitfähigen Lamellenring 65 zur elektrisch leitfähigen bewegbaren Verbindung mit dem zweiten Nennstromkontakt 55 einer Schalteinheit 3 auf. Figure 7 shows a sectional view of an embodiment of a second switching unit base 7. The second switching unit base 7 has a connecting flange 63 at its end on the connection housing side, which can be connected to an interrupter unit insulator tube 13, 14, 15. At the end facing away from the connection housing 17, the second switching unit base 7 has an electrically conductive lamellar ring 65 for electrically conductive, movable connection to the second rated current contact 55 of a switching unit 3.

Figur 8 zeigt die Schalteinheit 3, den ersten Schalteinheitssockeladapter 9 und den ersten Schalteinheitssockel 5 einer zweiten Unterbrechereinheit 32. Der erste Schalteinheitssockeladapter 9 ist röhrenartig ausgebildet und weist ein erstes Schalteinheitssockeladapterende 67 auf, das zum Tragen des ersten Nennstromkontakts 51 und des mit dem ersten Nennstromkontakt 51 verbundenen ersten Lichtbogenkontaktstücks 53 der Schalteinheit 3 ausgebildet ist. Ferner weist der erste Schalteinheitssockeladapter 9 ein zweites Schalteinheitssockeladapterende 69 auf, das mit dem ersten Schalteinheitssockel 5 verbunden ist. Figure 8 shows the switching unit 3, the first switching unit base adapter 9 and the first switching unit base 5 of a second interrupter unit 32. The first switching unit base adapter 9 is tubular and has a first switching unit base adapter end 67 which is designed to carry the first rated current contact 51 and the first arcing contact piece 53 of the switching unit 3 connected to the first rated current contact 51. Furthermore, the first switching unit base adapter 9 has a second switching unit base adapter end 69 which is connected to the first switching unit base 5.

Figur 9 zeigt eine Schnittdarstellung eines ersten Schalteinheitssockeladapters 9. Das erste Schalteinheitssockeladapterende 67 ist als ein erster Adapterflansch ausgeführt, dessen Außenoberfläche konvex gewölbt ist, um elektrische Felder abzuschirmen. Ferner weist das erste Schalteinheitssockeladapterende 67 Gewindebohrungen 71 zur Aufnahme von Schraubelementen 75 auf, mit denen es an einer Schalteinheit 3 befestigbar ist. Das zweite Schalteinheitssockeladapterende 69 ist als ein zweiter Adapterflansch ausgeführt, der Flanschbohrungen 73 aufweist, durch die Schraubelemente 75 führbar sind, mit denen das zweite Schalteinheitssockeladapterende 69 mit einem ersten Schalteinheitssockel 5 verbindbar ist. Die zweiten Schalteinheitssockeladapter 10 unterscheiden sich von den ersten Schalteinheitssockeladaptern 9 lediglich durch ihre Länge. Figure 9 shows a sectional view of a first switching unit base adapter 9. The first switching unit base adapter end 67 is designed as a first adapter flange, the outer surface of which is convexly curved in order to shield electrical fields. Furthermore, the first switching unit base adapter end 67 has threaded holes 71 for receiving screw elements 75, with which it can be fastened to a switching unit 3. The second switching unit base adapter end 69 is designed as a second adapter flange, which has flange holes 73 through which screw elements 75 can be guided, with which the second switching unit base adapter end 69 can be connected to a first switching unit base 5. The second switching unit base adapters 10 differ from the first switching unit base adapters 9 only in their length.

Figur 10 zeigt eine Schnittdarstellung eines mit einem ersten Schalteinheitssockel 5 durch Schraubelemente 75 verbundenen ersten Schalteinheitssockeladapters 9. In analoger Weise ist ein erster Schalteinheitssockeladapter 9 mit einer Schalteinheit 3 verbindbar. Figure 10 shows a sectional view of a first switching unit base adapter 9 connected to a first switching unit base 5 by screw elements 75. In an analogous manner, a first switching unit base adapter 9 can be connected to a switching unit 3.
